On-line monitoring device of lightning arrester of touch screen type switch cabinet with memory

Abstract

The invention discloses an on-line monitoring device of a lightning arrester of a touch screen type switch cabinet with a memory. The on-line monitoring device comprises a voltage and current collecting unit (1), a discharging times collecting unit (2), a central control processor (3) and a display screen (4), wherein the voltage and current collecting unit (1) is connected with the lightning arrester (4) in the switch cabinet and a capacitor type post inductor (5) by wires, and the discharging times collecting unit (2) is connected with a switch contact of a large current discharge protection device (6) on the lightning arrester (4). The on-line monitoring device has the beneficial effects that a wireless module is adopted, and a worker can receive the action information of the lightning arrester through a receiving terminal; when the wireless module has a fault, the action records of the lightning arrester can be freely looked up through the touch screen, and the defect of unable displaying of all action information of the lightning arrester due to oversmall size of the display screen is overcome; and LEDs (light emitting diode) for electric indication are connected in parallel, so the indication can be still realized if one LED is damaged.

Description

technical field [0001] The invention relates to a monitoring device, in particular to an on-line monitoring device for a touch screen type lightning arrester of a switch cabinet with a memory. Background technique [0002] The 10KV-35KV high-voltage switchgear is the most commonly used electrical equipment in the substation. At present, the display outside the cabinet is used to display the operation information of the arrester in the cabinet, but the staff generally do not record the operation information of the arrester frequently, and the display cannot display too much content. , so the staff need to take out the memory in the cabinet to read the information, which seems very troublesome. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the present technology, to provide an on-line monitoring device for the lightning arrester of a touch screen switch cabinet with a memory, and to adopt a wireless module, so that...
